Title: Nokia's Statement About IPR Claimed in RFC 3588 Received: January 6, 2004 From: harri.t.honkasalo@nokia.com This is to advise the IETF that Nokia believes the Nokia patents: EP1147635 and AU757984, and the related patent applications: BRPI0007603-1, CA2360093, CN00804050.8, FI990102, JP2000-595452 and US09/903863 may be relevant to Diameter Base Protocol RFC3588. Nokia agrees not to assert those claims in Nokia above mentioned patents that apply to the RFC3588 and are technically necessary to implement this IETF standard specification against any other party in respect of its implementation of the specification, provided that the party relying on this commitment does not assert its patents against Nokia.
